There are paid services and "free" ones (the latter are also paid for some moments). Paid is just a space price tag, specialists in very high self-esteem can allow the patient to say that they have not seen worse problems than his, that how can you run yourself like that, and it's terrible how much effort goes into it))) This is not the level and professionalism!!! Moreover, it was observed by one doctor, and had to be redone every six months, although the price tag is not very small.
